Yea I made the mistake of looking at the fish at walmart today. They had what was labeled as a green spotted puffer, but it was really a figure 8 puffer. It was the only 1 there, and has a minor case of ich. I just had to rescue it. So its in my QT tank right now being treated for ick until I get a tank new tank cycled for it. I can't believe I did that.
